SPECIFICATION forming part of Letters Patent No. 616,471, dated December 27, 1898. Application tiled May 8,1897. Serial No. 635,641. (No model.)

"o @ZZ lL/'hom it may concern:

Be it known that I, WILL M. KINNARD, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Paper Vessels, of which the followingr is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to an improvement in paper vessels, Vand has for its object to provide a simple, economical, and slop-proof pail or vessel of such a shape that a quantity of these vessels can be nested together to be substantially waterproof and durable.

It consists in certain modifications and improvements upon the vessel described in my application, Serial No. 019,408, as will be hereinafter more fully set forth in the following specification.

In the drawings, Figure l is a perspective view of my improved pail or vessel with the top in place, showing the clasps for regulating the position of the top. Fig. 2 is a perspective view of the same with the lugs or cushions for fastening the top in place. Fig. 3 is a cross-section of a part of the upper edge of the vessel, showing the construction of the clasp for fastening the lid. Fig. 4 is a crosssection of a part of the top, showing the construction of the clasp or clip for holding the lid in place and preventing its passing too far into the vessel. Fig. 5 is a crossesection of a part of the top, showing the hinge by which the lid is attached to the body of the vessel. Fig. (i is a cross-section of the same, illustrating the manner of attaching or hinging the lid to the vessel. Fig. 7 is a vertical crosssection of the pail, illustrating one forml of constructing the bottom or base. Fig. 8 is a similar vertical cross section showing another form of constructing the base. Figs. J and 10 are similar cross-sections showing modiiied forms of attaching the bottom.

The vessel as I construct it is made, preferably, in the shape of a pail or bucket-that is, circular in horizontal cross-section, but tapering outwardly from the base upward. It is constructed of paper, with double walls. These walls are formed by cutting out a blank which when curved so that the edges of the narrower ends meet, it will form a pail. The blank forming the outer wall is of course slightly longer than the blank forming the inner wall, as its diameter and circumference would be greater by the thickness of the paper used. The outer wall is applied to the inner Wall preferably in such a position that the seam formed by the meeting edges does not register with the seam formed by the meeting edges of the inner wall. I prefer to have these edges simply meet, because I can thus produce a smoother surface both outside and inside; but, `if it is desired, the edges of the blanks forming the outer and inner walls may be made to overlap, when, of course, they are securely glued to one another, and the outer and inner walls should also be attached to one another by some adhesive material.` A pail or vessel thus formed needs some sort of brace or stiffening at its upper edges, and I form this brace of a strip of tin or similar sheet metal, although it may be done with heavy paper, by folding the strip upon itself, so that its cross-section would resemble the letter U inverted. It is then slipped down over the upper edge of the vessel, one limb passing' on the outside and the other on the inside. Of course as the circumference or diameter of the inner limb is less than that of the outer when it is pressed tight home about the upper edges of the vessel it will buckle. To prevent this, I corrugate the inner limb, as shown in Figs. 7, 8, and 9, or a portion of the inner limb may be cut away but-I prefer to corrugate it. lVhen the pressure is applied to force this metal brace hard against the walls of the vessel, these corrugations, or rather the inner sharp edges of them, sink into the softersubstance forming the walls and serve to lock the brace tightly in place. The upper edges, therefore, of the vessel are thus made very strong and very firm and also very true to receive the lid and effect a tight, close joint between the walls of the vessel and the lid.

The lid I construct of a disk of paper or cardboard of sufficient stiffness, said disk being a little larger .in diameter than the top of the vessel. The outer edges of this disk are turned upward by placing the disk in a die of smaller diameter or in any convenient ICD way, producing an upwardly-extending rim or flange. The width of this ange of course depends upon the difference between the diameter of the vessel and the diameter of the disk used to form the top, and if it is desired to make the vessel specially tight the fiange should be made wider, because when the lid is in place this flange presses outwardly against the inside or walls of thepail, and by making the flange wider and dropping the lid that much farther into the vessel the space or extent of the contact between the walls of the vessel and the lid is increased. I prefer to have the lid hinged directly to the vessel, and I have shown in Figs. 5 and G an improved construction of this hinge.

A is a portion of the wall of a vessel; B, the metal brace, formed of a strip of sheet metal bent upon itself and in cross-section resembling the letter U, the two limbs of which embrace tightly the upper edges of the vessel A.

C is the lid; D, the upturned flange or rim around the edge of the lid. By leaving two small parts of the inner leg or limb of the brace B cut away and these portions standing upright I form small lugs, which can readily be bent down; I also attach to one portion of the iiange D of the lid C a short section of a similar brace, as shown at F, Figs. l and 2, a portion of which-and in this case a portion of the outer limbis cut away and left standing upright. Then the lid is inserted in the top of the vessel, the narrow upright portion or lug of the brace F, attached to the lid, is arranged to come between the two narrow upright portions of the brace B on the top of the vessel. By bending this lug, as shown in Fig. 6, at K, over and around a wire link L this link is securely attached to the lid. Then by bending over these lugs on the brace B, as shown at M, Fig. 6, and inserting them through the same link L and clenching them down fast against the inner side of the vessel I form a hinge, as fully illustrated in Figs. 5 and 6, which permits the lid to be folded back freely and yet holds it securely in place. No additional material is used except the very small piece of tin f, a portion of the brace B being used without in any way detracting from its strength and efficiency and the construction of the hinge being made thus infinitely simple and economical.

The lid C, should it become softened by moisture orany other cause, lnighthave atendency to sink down into the vessel too far. In order to prevent this, I provide stays to hold it in place, as shown at E in Figs l and 2. These stays consist of small pieces of sheet metal attached to the lid and bent over outwardly in the form of hooks, so that when the lid is adj usted to its proper position to close the vessel these stays E E will hook over the top edges of the vessel and limit the downward movement of the lid and hold it securely in place. The preferred method of attaching these stays E is illustrated in Fig. 4. Anarrow strip of tin is bent over the upper edge of the flange D, as shown at the point e. It passes up and over the top of the liange, down the outside of the flange and through the iiange, then up on. the inside of the iiange, and over the top of the ange again and itself to its outer end c', which extends out over the edge of the vessel.v

I provide a lock for holding the lid in place in the very simple manner by leaving small portions of the inner limb of the brace B cut away and standing upright. Then the lid has been put in place, these portions or legs are bent over and down tightly upon the flange D of the lid, as shown at B', Fig. 3, and at' B', Fig. 2. The lid of the vessel is thus securely locked in place.

It is important to make the joints between the bottom of the vessel and the walls as secure as possible and at the same time to produce as smooth and unbroken a surface as possible, and in Figs. 7, S, f), and IO I have shown the dierent means I have employed for that purpose. A is the outer wall of the vessel, and G the inner wall. In Fig. this inner wall is shallower than the outer wall G and stops at g. I is the bottom, which is formed of a disk of paper or cardboard of sufficient stiness and strength, with the edges bent up to form a liange whose width corresponds with the distance from g to the bottom of the outer wall, so that when this bottom I is placed within the outer wall A the upper edges of it will meet the lower edges of the inner wall G. Thiswould leave a seam extending through only the inner wall and closed by the outer wall, which may be sufficient. If, however', itis desired to make the vessel additionally secure, I use a guardstrip N. This strip N consists, preferably, of a narrow strip of the same material used to make the vessel and is inserted between the outer wall A and the lower edge of the inner wall G and the upper edge of the liange on the bottom I, so as to bring the joint between the upper edge of the tlange of the bottom and the lower edge of the inner wall G at about the middle of the strip N. serves to close effectually the seam and prevent all possible leakage.

Where it is found inconvenient to insert the strip N and in order to avoid having an exposed seam, I make the vessel with a double bottom, as shown in Fig. 8, the flange of the outer bottom P passing up outside of the outer wall of the vessel and the flange of the inner bottom O passing up inside of the inner wall. In Fig. 9 I have shown another form, in which the outer bottom Q is provided with an upturned liange,which passes between the outer and inner walls A and G, and an inner bottom R, whose flange passes up within the inner walls. In Fig. 10 the outer bottom S is provided with a flange S', which passes up outside of the outer walls the same as in Fig. 8; but the inner bottom T is provided with an This strip IOC IIO

A13o Y u pturned ila-nge passing up between the outer and inner walls A and G. In each of these Jforms I provide a bottom in which there is no exposed seam-that is, no seam extending entirely through the vessel. Each seam is effectually guarded and extends only through one thickness or wall, thereby preventing any possible leakage.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

l. A paper vessel whose upper edges are braced by a strip of sheet metal, the interior leg or limb of said brace being corrugated to prevent buckling and when pressed against the walls of the vessel, to slightly penetrate the paper and lock the brace in place, substantially as and for the purpose described.

2. A paper vessel circular in cross-section, provided with a hinged lid, said lid consisting of a disk of paper Whose outer edges are turned up at an angle to the body of the lid and having attached to this iiange a strip of sheet metal bent around one side of a link of Wire and back upon the other side of said flange, in combination with a lug attached to the outside of the Wall of the vessel and bent around the other portion of said link and back upon the inside of said wall to form a swiveled hinge, substantially as shown and described.

3. A paper vessel circular in cross-section and provided with double Walls and double bottom, the bottom consisting of two disks one Within the other, with upturned edges, the upturned edgesof these disks embracing the lower edges of one of the Walls of the vessel, substantially as and for the purpose described.

.L. A paper vessel circular in cross-section, provided with double Walls, the inner Wall shorter than the outer Wall at the bottom, and the bottom of the vessel consisting of a disk Whose edges are bent upward to meet the lower edges of the inner wall, in combination with a guard-strip inside of the outer Wall and opposite the seam formed by the meeting edges vof the inner wall and the bottom, substantially as and for the purpose described.
